China's second great wall, a vast seawall covering more than half of the country's mainland coastline, may be a foundation for economic growth but it can also result ecological disasters that can extend beyond China, says a study.

To protect its 1,600-km long coastline, Gujarat is all set to deploy an elite force of 1,000 'amphibious' marine commandos at strategic locations for surveillance at sea and the coast against threats like infiltration and drug trafficking, a first such initiative in the country.

The Indian Coast Guard (ICG)
is planning to have 42 stations across the 7,500-km-long
coastline for effective monitoring of maritime borderline, its
Director General and vice-admiral Anil Chopra, said on Wednesday.
